Beta, where art thou?

So....where is Legion Beta? I am not going to conclude that the game in itself won't be released 'til September, not just yet at least. However, I am confused as to why it is taking them so long to start Beta testing with the community at large. This will undoubtedly spur conversations about the reasons for which Beta isn't ready yet.
Maybe it is ready, by the way, but maybe not. That is my point. Players are going to start theorizing about maybe the expansion announcement and release being rushed out was so to cover up the terrible numbers of last years quarterly reports, when in fact Legion is still way off.

I will stop with the assumptions. But i am curious if anyone else is maybe worrying about Legion also being a one year lifespan, WoD like, expansion.

P.S: do not attempt to troll me, i am in no way shape or form trying to be hostile in discussing this issue :)
